I have a 2008 4DR Rubicon with 300 miles on it right now. Two weeks ago I installed a complete TeraFlex 4” Suspension Lift (Part #: 00145140), new 35” BFG KM2’s with new 17” rims and a new steering stabilizer. The kit came with everything to include a front adjustable track bar. This weekend I installed a new TeraFlex front driveshaft.
Ever since the kit has been installed I have been hearing a loud creaking noise that sounds like it is coming from all four corners of the jeep and every time I have a passenger, they say that they feel a bumping at their feet. There was no change to these noises with the new drive shaft. The only time that I hear this creaking is when I am driving slowly. It seems to be fine on the highway.
Does anyone know what this might be or how to fix it? I checked all of the bolts and thy are tight.
FYI- I have no experience with this type of work and I installed everything myself, so any tips or recommendations will be truly appreciated!
I also installed Rugged Ridge RRC Side Armor Guards before the lift, but they did not cause any noises.
THANKS!!

 

i would re tourque everything and than see if the noise is still there.
mine makes alotta noise, but i just turn up the radio

 

I have re torqued everything. Would you recommend using an impact wrench?

 

Dont use an impact to torque something down. You'll never really know how tight it is. Only use a torque wrench and make sure you torgue everything when the full weight of the jeep is on the ground.

 

This is exactly how I did it (minus the torque wrench) The kit did not specify the torque settings so I loosely tightend everything while lifted and then lowered it to tighten everything as tight as I could with a breaker bar.

 

If everything is torqued down is it possible it's something that needs to be greased, like swaybar links for something?

 

Did you use grease while installing the lift and or have you greased the fittings yet?

 

They appeared to be greased when I got them, but last night I used a grease gun and lubed them again. I drove around, but no change. Should I give it more time for the grease to set in?

What about the passenger floor bumping? Any thoughts?

 

Which 4" kit did you get? You mounted the rubber end on the frame side, correct?

 

The kit that I got was the TeraFlex 4” Suspension Lift (Part #: 00145140), you helped me over the phone a lot and I sent you pics of the rear control arms installed. This is Frank Deerr.

The control arms are mounted the way the directions said:

Front and Rear Lower Control Arms: Brass Universal Joint is on the Axle.
Front and Rear Upper Control Arms: Brass Universal Joint is on the Frame.
